Question

The equilibrium expression for a chemical reaction is Keq = [NOBr]2/[NO]2[Br2]. What is the reaction?
(Points : 3)
2NO (back and forth arrows) 2NOBr + Br2

2NO + Br2 (back and forth arrows) 2NOBr

Br2 (back and forth arrows) 2NO + 2NOBr

2NOBr (back and forth arrows) 2NO + Br2

Answer 1

What is a negative Gibbs free-energy value an indication of?
(Points : 3)
an enzymatic reaction

a reversible reaction

a spontaneous reaction

an equilibrium reaction

Answer 2

aA + bB \(\rightleftharpoons\) cC + dD

\(K_{fwd}=\dfrac{[C]^c*[D]^d}{[A]^a*[B]^b}\)

Answer 3

when \(ΔG<0\) the reaction forward is spontaneous
